In this paper we derive a fourth-order nonlinear partial differential equation modelling the effects of suction/blowing on the evolution of the free surface of a thin viscous film on a porous base. Gravity and surface tension effects are included. The suction/blowing is modelled as an arbitrary function vn(t, r). The Lie group classification method is used to determine a firstorder quasi-linear...

In [M], Mainò constructed a moduli space for enriched stable curves, by blowing-up the moduli space of Deligne-Mumford stable curves. We introduce enriched spin curves, showing that a parameter space for these objects is obtained by blowing-up the moduli space of spin curves.

The nasopharynx (NP) is the preferred site for detection of Streptococcus pneumoniae in young children, but NP sampling is not well tolerated. We compared nose blowing with paired nasal swabs. The sensitivity of nose blowing was 46% (95% confidence interval [CI] 38 to 56%), which increased to 94% (95% CI, 85 to 98%) for children with visible secretions.

We apply mathematical modelling to study heat transfer processes during fire refining of blister copper in a ladle-furnace unit. A unit was designed test the technology using bottom blowing bubble mode by gaseous reducing agents (hydrocarbons) and an oxidiser. Mathematical allows properties real process be described based on formalisation physical laws regularities. It proposed use agents, rath...

This paper discusses a study of the effects of pylon trailing edge blowing on pusher propeller performance and noise emissions. Experimental investigations were performed in a low speed open jet wind tunnel, using a powered propeller model and a generic pylon model. A novel pylon blowing system was integrated in the aft part of the pylon to provide a uniform outflow. The numerical analysis was ...

In this talk we discuss sector decomposition. This is a method to disentangle overlapping singularities through a sequence of blow-ups. We report on an open-source implementation of this algorithm to compute numerically the Laurent expansion of divergent multi-loop integrals. We also show how this method can be used to prove a theorem which relates the coefficients of the Laurent series of dime...

Purpose: To evaluate the technique sensitivity of four different adhesive systems using different air blowing pressure. [LP] (3M ESPE, USA) and an experimental adhesive, SSB-200 [SSB] (Kuraray, Japan). Twenty-four extracted molars were used. After grinding the coronal enamel surface, the teeth were divided into two equal groups. The first group's teeth were randomly assigned for bonding with th...

Leniency clauses, offering cartelists legal immunity if they blow the whistle on each other, is a recent anti-trust innovation. The authorities wish to thwart cartels and promote competition. This effect is not evident, however; whistle-blowing may enforce trust and collusion by providing a tool for cartelists to punish each other. We examine the impact of leniency law, and other rules, theoret...

The paper presents a numerical analysis of thick-walled PA66 GF30 moldings with the addition chemical blowing agent content 1-3 wt%, and obtained results were compared real object. Computer simulations performed using Moldex3D ® software. Based on analysis, it was found that regardless dose used, largest pores place in core sample. Moreover, size depends their number cross-section moldings. Com...
